Close Homologs in the Non-Redundant Database Detected by BLAST
Members of this protein family, rich in coiled coil regions, are molecular chaperones in the class of the prefoldin (GimC) alpha subunit. Prefoldin is a hexamer of two alpha and four beta subunits. This protein appears universal in the archaea but is restricted to Aquifex aeolicus among bacteria so far. Eukaryotes have several related proteins; only prefoldin subunit 5, which appeared the most similar to archaeal prefoldin alpha, is included in this model. This model finds a set of small proteins from the Archaea and from Aquifex aeolicus that may represent two orthologous groups. The proteins are predicted to be mostly coiled coil [Protein fate, Protein folding and stabilization]. Length = 126

This family comprises of several prefoldin subunits. The biogenesis of the cytoskeletal proteins actin and tubulin involves interaction of nascent chains of each of the two proteins with the oligomeric protein prefoldin (PFD) and their subsequent transfer to the cytosolic chaperonin CCT (chaperonin containing TCP-1). Electron microscopy shows that eukaryotic PFD, which has a similar structure to its archaeal counterpart, interacts with unfolded actin along the tips of its projecting arms. In its PFD-bound state, actin seems to acquire a conformation similar to that adopted when it is bound to CCT. Length = 120

Prefoldin (PFD) is a chaperone that interacts exclusively with type II chaperonins, hetero-oligomers lacking an obligate co-chaperonin that are found only in eukaryotes (chaperonin-containing T-complex polypeptide-1 (CCT)) and archaea. Eukaryotic PFD is a multi-subunit complex containing six polypeptides in the molecular mass range of 14-23 kDa. In archaea, on the other hand, PFD is composed of two types of subunits, two alpha and four beta. The six subunits associate to form two back-to-back up-and-down eight-stranded barrels, from which hang six coiled coils. Each subunit contributes one (beta subunits) or two (alpha subunits) beta hairpin turns to the barrels. The coiled coils are formed by the N and C termini of an individual subunit. Overall, this unique arrangement resembles a jellyfish. The eukaryotic PFD hexamer is composed of six different subunits; however, these can be grouped into two alpha-like (PFD3 and -5) and four beta-like (PFD1, -2, -4, and -6) subunits based on amino acid sequence similarity with their archaeal counterparts. Eukaryotic PFD has a six-legged structure similar to that seen in the archaeal homologue [, ]. This family contains the archaeal alpha subunit, eukaryotic prefoldin subunits 3 and 5 and the UXT (ubiquitously expressed transcript) family. Eukaryotic PFD has been shown to bind both actin and tubulin co-translationally. The chaperone then delivers the target protein to CCT, interacting with the chaperonin through the tips of the coiled coils. No authentic target proteins of any archaeal PFD have been identified, to date.; GO: 0051082 unfolded protein binding, 0006457 protein folding, 0016272 prefoldin complex; PDB: 1FXK_C 2ZDI_C.

The structure of the complex consists of a double beta barrel assembly with six protruding coiled-coils.
Chaperonins are cytosolic, ATP-dependent molecular chaperones, with a conserved toroidal architecture, that assist in the folding of nascent and/or denatured polypeptide chains. The group I chaperonin system consists of GroEL and GroES, and is found (usually) in bacteria and organelles of bacterial origin. The group II chaperonin system, called the thermosome in Archaea and TRiC or CCT in the Eukaryota, is structurally similar but only distantly related. Prefoldin, also called GimC, is a complex in Archaea and Eukaryota, that works with group II chaperonins. Members of this protein family are the archaeal clade of the beta class of prefoldin subunit. Closely related, but outside the scope of this family are the eukaryotic beta-class prefoldin subunits, Gim-1,3,4 and 6. The alpha class prefoldin subunits are more distantly related.

Prefoldin binds and stabilizes newly synthesized polypeptides allowing them to fold correctly. The hexameric structure consists of a double beta barrel assembly with six protruding coiled-coils. The alpha prefoldin subunits have two beta hairpin structures while the beta prefoldin subunits (this CD) have only one hairpin that is most similar to the second hairpin of the alpha subunit. The prefoldin hexamer consists of two alpha and four beta subunits and is assembled from the beta hairpins of all six subunits. The alpha subunits initially dimerize providing a structural nucleus for the assembly of the beta subunits. In archaea, there is usually only one gene for each subunit while in eukaryotes there two or more paralogous genes encoding each subunit adding heterogeneity to the st

DegQ is 46 amino acids long and activates the synthesis of degradative enzymes. The expression of this peptide was shown to be subjected both to catabolite repression and DegS-DegU-mediated control. Thus allowing an increase in the rate of synthesis of degQ under conditions of nitrogen starvation [].
